How to Get to Red Mountain 3 Trailhead
The Red Mountain 3 trailhead is located along Red Mountain Pass in the San Juan Mountains, between the towns of Silverton and Ouray, Colorado.
To reach it, most hikers drive through the famous Million Dollar Highway, which is one of the most scenic mountain drives in the United States. The road itself is narrow and winding, but it offers stunning views throughout the journey.
From Silverton, you head north on Highway 550, and from Ouray, you head south. The trail access is typically found along roadside pullouts near the Red Mountain Pass area.
Parking is limited and informal. Most hikers park on the side of the road or at small pull-off areas, so it’s important to arrive early, especially in peak hiking season.
For navigation, GPS is highly recommended because there is no clearly marked official trailhead. Many hikers rely on GPS coordinates and offline maps to stay on track, as the terrain can be confusing once you leave the main road.
Step-by-Step Hiking Route Description
The Red Mountain 3 hike does not follow a perfectly marked trail, so understanding the route is very important before you start.
Starting point overview
Most hikers begin near Red Mountain Pass along Highway 550 in the San Juan Mountains, Colorado. The starting point is usually an informal roadside pull-off, not a dedicated trailhead, so it can be easy to miss if you are not paying attention.
Trail progression breakdown
From the start, the route begins with a gradual climb through rocky and uneven terrain. As you gain elevation, the path becomes steeper and less defined. Hikers often move between natural clearings and rocky slopes rather than a single visible trail.
